UNITED STATES PATENT OFFICE.

JOHN G. FINDLEY, OF IVALLAOEBURG, ONTARIO, CANADA.

GAGE-COCK.

SPECIFICATION forming part of Letters Patent No. 414,034, dated October 29, 1889.

Application filed June 29, 1889. Serial No. 316,026. (No model.)

To all whom, it may concern:

Be it known that I, JOHN G. FINDLEY, of Wallaceburg, in the county of Kent, Province of Ontario, Canada, have invented a new and useful Improvement in Gage-Cocks, of which the following is a specification.

My invention consists in an improvement in gage-cocks, hereinafter fully described and claimed.

Figure l is a side elevation; Fig. 2, a longitudinal vertical section; Fig. a plan view, omitting the plug; Fig. 4, an elevation of the plug; Fig. 5, a plan view of the same; and Fig. 6 is a side elevation of the cock, showing the swinging head elevated to permit escape of steam. e

F represents the screw-threaded stem of the cock, having therein the longitudinal bore G and provided with the usual shoulder H for screwing the same into the boiler.

O represents a swinging head having the weighted end E and pivoted to the stem F by the pin I.

Instead of having a simple seat in the head 0 for the reception of packing to bear against the end of the stem F, I form in the head O the cylinder D, in which is inserted a plug A, formed like the plug of a stop-cock, and with a handle whereby the plug may be turned and flatten the opposite sides of plug A, as clearly indicated in Fig. 5, to receive two separate and independently-removable packingstrips B, of rubber or other suitable substance. I preferably make each packing-strip a little wider than the slot in head 0, which embraces the end of the stem F, so that said packing B is all times held in the cylinder D.

.In use one strip of packing B rest-s against the end of stem F, closing the bore G in the ordinary manner.

When it becomes necessary to renew the packing in a gagecock of an ordinary kind, the head 0 must be raised, and if there is steain pressure on the boiler steam issues from the bore G with violence and the engineer is liable to be scalded. With my invention all that is necessary is to turn the plug A until the other strip of packing B closes the bore G, when the Worn-out strip of packing may be removed and a fresh piece inserted, the gage-cock remaining closed.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a gage-cock, the combination of ahollow stem, a head pivoted to said stem, and a rotary plug having separate and independently-removable packing-strips on two sides thereof, substantially as shown and described.

2. In a gage-cock, the co mbination,'with the stem F, having therein the bore G, of the head O, pivoted to said stem and having therein the cylinder D, and the rotary plug A, carrying the separate and independently=removab1e packing-strips B B, substantially as shown and described.
